He was rich, powerful and every woman's fantasy. Although many had tried to lasso Jacobsville's sought-after bachelor, none had managed to catch Matt Caldwell's eye. However, mysterious Leslie Murry was about to change all that. For the cynical Texas tycoon's spirited new employee roused his temper like no one ever had before. And despite his fierce denials, her soft vulnerability also brought out his every protective instinct. After sampling her soul-searing kisses, Matt was sorely tempted to possess the enticing innocent who clearly ached for a man's tender touch. Still, this Long, Tall Texan wasn't about to let down HIS guard until he sweet-talked Leslie into surrendering HER heart! Long Tall Texans: Rugged heroes from Jacobsville, Texas.

Matt Helm finds himself in Hawaii, trying to unhatch a plot of unrivalled viciousness. When an agent turns bad, nobody's business is private anymore, and when that agent decides to start a war, someone has to finish him--fast. Between the rogue agent and the stranger who insists she is his sister-in-law, this won't be a relaxing Pacific holiday.

It was a double mission this time. Firstly, to terminate a top-notch enemy agent. Secondly, to locate the missing fiancée of a Texas oil millionaire, lost in the Bermuda Triangle. Somehow these two cases were connected, but it wasn't clear how until more high-profile types disappeared. They weren't dead, just part of a deadly little game...

Matt Helm is puzzled. He's been sent to Mexico to investigate the sighting of a flying saucer, but Helm doesn't believe in little green men. Then his Russian opposite number is shot in her hotel, but who did it? And why are the Mexican cops acting so tough? Time to track down the redhead who called in the sighting and get to the bottom of the case.

When Matt Helm is dispatched to Los Angeles to investigate the shooting of an agent, it wasn't just an assignment--it was personal. To get the answers he wants means run-ins with two-bit hoods, a trio of beautiful women, a bunch of drug traffickers, and his old friend Mr Soo, whose government has ideas about polluting America to death...

A year after having been reactivated, Matt Helm receives a message from his ex-wife, asking for his aid. The threat is an enemy agent named Martel, disguised as a mob hitman. To protect his family, Helm must "remove" the threat before his own children pay the ultimate price.

Matt Helm, code name Eric, has been recently reactivated as an operative for a secret American government organization after 15 years as a sedentary photographer and family man in Santa Fe, New Mexico. In his first assignment after returning to the service, he is sent to Sweden to eliminate Caselius, a long-time enemy agent. In order to do so, he must leave a trail of bodies in his wake.

WILLIAM W. JOHNSTONE'S BREATHTAKING MOUNTAIN MAN SERIES SET THE STANDARD FOR WESTERN ADVENTURE. NOW A NEW SAGA BEGINS AS THE ADOPTED SON OF SMOKE JENSEN TAKES HIS PLACE ON THE UNFORGIVING AND VIOLENT AMERICAN FRONTIER...
BORN TO BE BRAVE.
Matt Cavanaugh was nine years old when a band of outlaws slaughtered his family...Now Matt is 18, honed by hardship, steeped in survival and carrying the last name of the man who raised him: Smoke Jensen. With Smoke's wisdom, his own courage and just enough money to start a life, Matt Jensen begins a relentless hunt for the outlaws, led by the deadly Winston Pugh, who murdered his family in cold blood. Pugh won't be hard to find; his scarred face gives him away. But Matt soon discovers there's a lot more to vengeance than hunting down a man--and that in a clash of guns and guile, true justice is waiting just beyond a town called Perdition...

WILLIAM W. JOHNSTONE'S BREATHTAKING MOUNTAIN MAN SERIES SET THE STANDARD FOR WESTERN ADVENTURE. NOW, A NEW SAGA BEGINS, AS MATT JENSEN, THE ADOPTED SON OF SMOKE JENSEN, BLAZES A NAME FOR HIMSELF ON THE LAWLESS FRONTIER...
THE WAY OF THE GUN.
He'd done the old man proud. By leaping into the path of danger, Matt Jensen foiled a train robbery in Colorado, and the governor himself presented him with a public reward. But what started on the rails has stayed on the rails--and taken on a life of its own. Now, a frustrated outlaw and his murderous posse have struck again--this time kidnapping the governor's niece. With the power of the law behind him, Matt Jensen, the last mountain man, is riding toward a town called Braggadocio. That's where Matt will learn how to put a bad man down--and to make sure he stays that way...

Purgatory Arizona, is the last place you'll ever cross the law. Because in this town, the law is the personal fiefdom of an evil man--as Matt Jensen discovered on his first day in town, when an unavoidable gunfight and a dead deputy landed him in jail, sentenced to hang at Yuma Prison. But when the train from Purgatory to Yuma is violently derailed, Matt is set free amidst the carnage--with a choice to make. He can run for his life and live like an outlaw or take a chance with the determined U.S. marshal who must hunt him down. For Matt, the choice will be easy. Because when both he and his pursuer tangle with a vicious band of outlaws, they're both caught on the same bloody trail...that leads straight back to Purgatory.

It was a duty to a dead man. Matt Jensen had promised his friend, slain by an outlaw named Pogue Willis, that he would deliver money to his brother in St. Louis. But Matt's search leads him from St. Louis to Arizona Territory, and into the company of a rich Easterner and his beautiful young wife. For Matt, the schemes of some citified land prospectors don't mean much, until the young woman is seized by renegade Apaches and it's up to Matt to save her from a brutal death...
Soon, Matt Jensen is learning a lesson in courage, betrayal, and fate--the fate that brought this woman to his side--and is bringing a killer named Pogue Willis all the way to a savage territory...with more killing on his mind.
